If electrons repel then why are particles attracted to each other so why do particles attract and what is the ratio of the gravitational attraction to the electric repulsion of both an atom and an electron? Thanks!

No what I meant is atoms alone and electrons alone. Do atoms repel? That is my question. And I meant by the ratio is the ratio ratio of the gravitational attraction to the electric repulsion of an electron, and the other ratio for atoms if an electric repulsion exists. I am sorry for phrasing that improperly and I hope you now get my point, I will try to do a better job of phrasing statements next time.ZapperZ said:There appears to be a lack of logic in this question, and I don't think this has anything to do with "quantum physics" where it was posted.
1. Yes, electron repels OTHER electron. But why would it puzzle you that electron and proton attract? After all, they have opposite charge to each other. So to answer your question on why they attract, it is because they have OPPOSITE charge, unlike electron and another electron.
2. "electric repulsion of both an atom and an electron"?? What is this and what gave you the idea that a neutral atom and an electron have a repulsion?
3. The calculation of the electrostatic force and gravitational force are not that difficult. Put two electrons at a distance from each other, and then use the Coulomb force to calculate the repulsive force, and the universal law of gravitation to calculate the attractive force.
Zz.

DEvens said:Actually, it's a puzzle for grad students studying quantum field theory. Why do like charges repel and unlike attract? They both interact through exchange of a photon. So how can bouncing photons back and forth cause attraction in one case and repulsion in the other?
Think about two guys, each sitting in a row boat, and the boats are sitting on a lake. If they throw a baseball back and forth, it will cause them to get farther apart. Each will have to push the ball in the direction of the other, so getting a back reaction. And each will catch the ball coming from the other, again causing a back reaction. So the naïve expectation from normal experience is, tossing photons back and forth should cause repulsion.
The answer is actually pretty tricky, and arises in the fact that the electric field is a quantum field of virtual particles.
ZapperZ said:Do you think this is the level that the OP is asking about? If you did, I certainly missed it in what has been written.
The electric repulsion of electrons refers to the force that causes two negatively charged electrons to repel each other. This force is a result of the electric field surrounding each electron and is described by Coulomb's law.
The electric repulsion of electrons plays a crucial role in determining the structure of atoms. As electrons repel each other, they occupy different energy levels and orbitals around the nucleus, resulting in the distinct electronic configurations of different elements.
The attraction between electrons is caused by the opposite charges of the particles. Since electrons have a negative charge, they are attracted to positively charged particles, such as protons in the nucleus of an atom.
The electric repulsion of electrons is responsible for the formation of chemical bonds. When atoms share or transfer electrons, the repulsion between their negatively charged electrons is balanced out by their attraction to the positively charged nuclei, resulting in a stable bond.
Yes, the electric repulsion of electrons is a fundamental force that is harnessed in many technologies, including electronics and electricity. Understanding and controlling this force is crucial in designing and developing various devices and systems that rely on the movement of electrons.
